Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990174, here are decompositions:

5 + 990169 = 990174
11 + 990163 = 990174
23 + 990151 = 990174
37 + 990137 = 990174
131 + 990043 = 990174
137 + 990037 = 990174
151 + 990023 = 990174
173 + 990001 = 990174

Showing the first eight; more decompositions exist.
